Patrick Long, from Bellaire, Fla., earned a Pirelli World Challenge weekend sweep overall and in the GT class on Sunday at Infineon Raceway in the Cadillac Grand Prix of Sonoma - Round 10 of the 2011 season. Ben Crosland, from Salt Lake City, made a late-race pass for the GTS win, with Aaron Povoledo leading every lap to earn the victory in Touring Car.

With the grid set based on lap times during Saturday's first race of the doubleheader weekend, Long started from pole in his No. 45 Privacy Star/TruSpeed and pulled away from the field at the as the lights went out. A pair of Cadillacs driven by Andy Pilgrim and Johnny O'Connell gave chase, but Long opened up a gap that settled between one and two seconds for most of the race.

Each time Pilgrim's No. 8 Cadillac Racing Cadillac CTS-V Coupe appeared poised to catch the leader, Long worked his Porsche through traffic and stretched his lead again. When the checkered flag waved after 27 laps, Long had earned a 1.586-second win. Long averaged 82.520 mph over the 60.615-mile race, and turned the fastest lap of the race in 1:35.914 (84.263 mph).

The weekend sweep gives Long four wins this season and a GT Drivers' Championship lead with two races remaining in the season.

"It's a big weekend, this is very timely," Long said. "It was more work than maybe the gap shows in both of those races, especially today. Traffic didn't go my way, and that's not anybody's fault, it's just racing. That's what makes it challenging. Racing Andy, he was really good on the Brakes and I'm racing with maximum [REWARDS weight] so I had to work to make the brakes and tires last.

"This is a good track for us. We're going to be licking our wounds a little bit the next two weeks at the big courses, but this is what we needed to do for points. We're going to race for a win all the way to the end of the year, we're not going to be points racing because it's too competitive. It was a tremendous honor to run with the Cadillac boys this weekend and the TruSpeed guys have given me everything I've asked for this season. It's a tremendous effort for everybody collectively and it's great to be part of this series."

While Pilgrim chased Long, he also had to hold off a charge from drivers
